When scanning the bar code, the part number is loaded to this field. When making a manual arrival reporting, you can use the drop-down list box to select any of the part numbers on the order.
If you select a row where the rest quantity is zero, the row will be highlighted in red. This indicates that no further registration can be made on that row. When loading the selected row, the program will fill in the part number. The previously delivered quantity and rest quantity for the row will also be loaded to the information section of the window.
